Air filters

[Dave]

Haha I used to LIVE for the de-filter, because I couldnt give a shite about my blocks, but over time it does score your bores a little... I did 15K with no filter, and the block was fine, but on head removal you can see it has scored the bore a tiny bit, plus it probably dosent do the turbo any good, and you run the risk of ingesting stones and children.

For testing to see if it makes power difference go for it, but long term have a BFO intake pipe and filter....
